y `To all' whom t may Concern.'

Be it known that I, DANIEL E. SNYDER, a citizen of the UnitedA States, residing at Roseland, in the county of Adams and'State of Nebraska, have invented certain newand useful improvements in Antiskid Devices for Vehicle Wheels, of which the following Yis a specification. n

v This invention relates to an improvedV anti-skid device, which isadapted more particularlyk for use upon automobile wheels.

rlhe principal object is to provide a structure embodying a plurality of individual traction members permanently mounted upon the axle in a manner to permit them to be racked in side byy side relation to dispose them in anl out-of-the-way position when not in use.v f

Briefly, the invention comprises a `permanently mounted annulus having a, guide way inl which roller bearings on the inner ends of the traction members are received,

means being provided and extending into said guide way, so that upon proper 1nanlipulation the bearings may be caused to ride out of the guideway to hang the hooked ends of the traction members upon a stationary rack.

Advantages derived from this arrangement will become apparent from the following` description and drawings.

In the accompanying drawing, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a side view of an automobile wheel showing the braking means, together with the improved traction device mounted thereon.

Figure 2 is an enlarged detail section showing a portion of the device.

Figure 3 is a side elevation of the aforesaid annulus.

In the drawings, the reference character 1 designates an end flange on an aXle housing, and 2 designates the brake band operated by the usual operating rods 3. The tire is represented by the reference character 4. The spokes have been omitted, for clearness.

Surrounding the flange 1 is an annulus 5. As before stated, this annulus ,is rigidly fastened to the flange l and this is accomplished by providing the annulus' with, attaching ears 6, which are bolted 'or otherwise iixedly mountedL in place. The annulus is formed in one side vwith la channel 7, constituting a guide or trackway. At the' top, a portion of the periphery is cut out, and an arcuate block 8 is pivoted between its ends in this cut-out portion. The block is preferably mounted uponl ak rod 9 which .is carried to a convenient point within reach of the driver to permit it to be rocked to throw the block upon anangle .and to dispose it in alignment with the guideway 7. r)This block vis formed with an arcuate groove V1,0, which is adapted to align Vwith ther trackway.

Formed integral with the annulus and eX- tending upwardly therefrom adjacent the 'block is a bracket arm ll having an inclined angularly directed free end portion" v12.

This bracket actually functions as a rack,

scription goes on.

The traction members are indicated bv the reference characters 13. VThese are in the form. of individual wires bent at 'their outer ends to provide portions 14E, fitting over the tread of the tire. The opposite inner ends are directed angularly'and provided with antifriction roller bearings 15, of a size to be snugly received in the trackway'7.

Assuming that the traction wires are distributed about the'tire in the approximate relation shown in Figure l, and that it is desired to move them in inoperative positions, the rock shaft 9 is rotated, in a direction to tip the grooved block, upon an' angle, so Vthat the groove 10 therein is in alignment with the trackway 7. Ordinarily, the block is in the horizontal disaligned position shown in Figure 3 and does not interfere with circular travel of the roller bearings in the track. However, as soon as the block is run crosswise of the track, it is obvious that the roller bearings, instead of following the course around the track will ride into the groove, will stack against each other, and the hooked ends thereof will be racked upon the finger 12 of the bracket 11. The bracket is of a size to permit all of the traction wires to be racked thereon. A consideration, in connection with the drawings, will enable persons skilled in the art to which the invention relates to obtain a clear understanding of the same', Ivherefora a more lengthy description is thought unnecessary;

as will be more clearly apparent as the de- `While l have shown the preferred e111n bodiment of the invention is to be understood that various changes in the ehnpe and arrangement of parte muy be reeorted to, without departing 'from the spirit of the invention or the Scope of the zippendd Claims.

Havingu thus described by invention, what I claim as .new is:

1. In zin zinti-slid device, in combinations en axle, an nnnnlue iiiiedly mounted upon the end portion of the axle, said annuler; be ing,1 provided with n groove forming n truckn wey, und n plurelitgT oi anti-slipping inem bers provided on inner ends with enti-frietion roller bearings movable in seid trechwziy, the outer ende of said members being,` provided with portions extending` over the treed of the tire to aiord traction.

2. In an enti-skiiii device, in combination, en axle housing, zin annulns lixediy mounted upon the flanged portion of the houeing, seid zinnulus being provided with n groove forming e traekway, and L plnrzilit;7 et entislipping,l members provided on inner ends with enti-friction roller bearings movable in seid treelmvzry, the outer ends of eaxid membere` being provided with port-ions extending over the tread of the tire to :ill'ord traction, and ineens carried by seid nnnnlus, whereby seid traction members may be Lemire 'neked thereon to dispoee them out oil the Way when not in use. o

3. il Structure of the chiefs deeeribed com` prising :in :innulus formed in one :side with n groove providing- :i traelmvey, e bloeli roeimbly mounted upon sind annulue und provided with en arcuate groove adapted to be disposed in alignment with seid breekvvzry, end :1n erm rigidly connected with enid ennnlns and having it free end erected zrngnlairlj. to provide n rack finger.

Ail. A :structure of the class deseribed com prieing :in nnnulus formed in one eide with e groove providing :i treelwey, n block roelmbly mounted upon maid :munies end provided with un :ufeuzite groove adapted 'to be disposed in alignment with said 'trechmly, en arm risgidlyY connected with enid :innidns and haring its free end ereeted engiderljv to provide zi reel: lingera and :L pliiralit,7 of individuel traction membt having hooks formed at their outer ende adapted to cooperate with the tread oi :i tire, and having their inner ends; dir'"` zingnlzirljz, and roller bearings Carried by seid lasst named ende` and litt-ed in Seid traclmvaiy.

In testimony whereof ,l :diix my signieture.
